These beautiful puppies are the pairing of Abigail Adams of Covenant Farm (Abby) and Ragnar Lodbrok (Rags) of Covenant Farm. Both of these parents have excellent temperaments and intelligence. Abby is an AKC registered purebred English Lab. She is the great-great granddaughter of our own Kelsey & Rob Roy, both long-since retired. Rags is an F1 Mastador (1st generation), and is in fact, Abby's son. We did not plan this breeding, and would never deliberately breed dogs that are related, although it is common practice amongst show dog breeders. Expect these pups to mature in the 100-150 lb. range as adults. See below for more information on Abby & Rags.

Dam & Sire: Abigail Adams & Ragnar Lodbrok of Covenant Farm


Abigail Adams of Covenant Farm

Abby is our only Labrador Retriever. She has classic English Lab features and temperament. She has a medium-high drive. She's very intelligent, playful and adventurous. Abby adores children, and all other dogs (if they will have her). She has a beautiful soft yellow coat. This is the first breeding of Caesar & Abby, and moree are planned.

Ragnar Lodbrok ("Rags") of Covenant Farm

This is Rags' first litter to sire. Unfrtunately, his first time was with his mom, Abby! While "line-breeding" is not unusal amongst show breeders, we never deliberately breed to a relative. Abby's cycle came in nearly a full month early, and we never knew it happened! Rags is a big, blocky-headed lad, weighing in at about 130# at one year old. He's a sweet lad with an affectionate and submissive nature, and medium enegy and drive. His dad is Benjamin, the English Mastiff stud we use for Abby.
